AI Technical Summary

Technical Problem

Existing filtration devices are prone to clogging during the filtration process, and the filter screen is fixed inside the device, making cleaning and replacement inconvenient and affecting work efficiency.

Method used

Multiple filter cartridges rotate inside the filter box by a motor-driven gear. The position of the arc-shaped locking block is controlled by a double cylinder to achieve the positioning and stability of the filter cartridges. The rotating door and connecting groove facilitate disassembly and installation. The arc-shaped filter screen enhances the filtration capacity, the drain trough drains accumulated liquid, and the support base improves the stability of the device.

Benefits of technology

It solves the problem of filter clogging, improves filtration capacity and stability, reduces the need to replace filter screens, and increases work efficiency and the service life of the device.
